Can somebody solve this: x^4+2x^3-25x^2-26x+120
Dafna11 [192]

Answer:

 (x + 5) • (x + 3) • (x - 2) • (x - 4)

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   1 • 15 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8

     -3    +    -5    =    -8

     -1    +    -15    =    -16

     1    +    15    =    16

     3    +    5    =    8    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  3  and  5

                    x2 + 3x + 5x + 15

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x+3)

             Add up the last 2 terms, pulling out common factors :

                   5 • (x+3)

Step-5 : Add up the four terms of step 4 :

                   (x+5)  •  (x+3)

            Which is the desired factorization

 (x + 5) • (x + 3) • (x - 2) • (x - 4)

A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- sc
Rashid [163]

A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- score is 0.40.

Answer: The given z-score is false.

Explanation: We are given:

Mean, \mu=100,

Variance, \sigma^{2}=25

\therefore\sigma=\sqrt{\sigma^{2}}

                 =\sqrt{25}

                 =5

The z-score formula is given below:

z=\frac{x-\mu}{\sigma}

        =\frac{110-100}{5}

        =\frac{10}{5}

        =2

Therefore, the z-score corresponding x=100 is 2

Therefore, the given z-score = 0.4 is false.

Give an example of a subordinating conjunction?
makkiz [27]
A subordinate conjunction<span> performs two functions within a sentence. First, it illustrates the importance of the independent clause. Second, it provides a transition between two ideas in the same sentence. The transition always indicates a place, time, or cause and effect relationship.

Hope that helps:)</span>
